[Cerebral venous thrombosis].

Cerebral venous thrombosis represents less than 1 % of all strokes, usually affecting young women, probably because of hormonal factors. The most common symptom is headache, with or without focal neurological findings such as deficits or seizures. Brain MRI is the gold standard for diagnosis. Anticoagulation should be initiated as soon as possible, followed by vitamin K antagonists, for at least 3 months. Predisposing causes and risk factors for cerebral venous thrombosis are multiple. Prognosis is good and recurrence rate is low.
